本文介绍如何利用Python进行历史天气数据的采集与分析。通过编写脚本获取天气信息，并将数据存入MySQL数据库及Excel文件中，为后续趋势分析提供数据支持。文章包含完整代码示例，适合对数据抓取和存储感兴趣的开发者参考。

对历史天气数据进行趋势分析。

首先需要执行数据采集步骤。

具体实现代码如下：

import requests
import random
import MySQLdb
import xlwt
from bs4 import BeautifulSoup

myfile=xlwt.Workbook()
wtable=myfile.add_sheet(u"历史天气",cell_overwrite_ok=True)
wtable.write(0,0,u"日期")
wtable.write(0,1,u"最高温度")
wtable.write(0,2,u"最低温度")

db = MySQLdb.connect('localhost','root','liao1234','liao',charset='utf8')
cursor = db.cursor()
 
index = requests.get("http://lishi.tianqi.com/binjianqu/index.html",headers=headers)
html_index = index.text
index_soup = BeautifulSoup(html_index)
i = 1
for href in index_soup.find("div",class_="tqtongji1").find_all("a"):
  print href.attrs["href"]
 
 
  url = href.attrs["href"]
  r = requests.get(url,headers = headers)
  html = r.text
  #print html
  soup = BeautifulSoup(html)
  ss = []
  s = []
  for tag in soup.find("div",class_="tqtongji2").find_all("li"):
    print tag.string
    s.append(tag.string)
    if len(s) == 6:
      ss.append(s)
      s = []
  flag = 0
  for s in ss:
    if flag == 0:
      flag = 1
      continue
    else:
      sql = "insert into weather(old_date,hight,low,weather,wind,wind_power) values('%s','%s','%s','%s','%s','%s')"%(s[0],s[1],s[2],s[3],s[4],s[5])
      cursor.execute(sql)
      wtable.write(i,0,s[0])
      wtable.write(i,1,s[1])
      wtable.write(i,2,s[2])
      wtable.write(i,3,s[3])
      wtable.write(i,4,s[4])
      wtable.write(i,5,s[5])
      i += 1
myfile.save("weather.xls")
db.close()
